[Mario Party-adjacent Shenanigans]



"I'm so happy you all came! Sorry to make it so sudden, but Yumeko's out of town for a bit, and Saeko didn't feel safe with just me around. Ehe, this is going to be the best sleepover!"



"I'm more than happy to come and help Saeko. You as well, Mikai. I'd love to hear what you two have gotten up to, now that your relationship has taken a turn like this."



"...Oh my god, Ero didn't mention it was a sleepover..."



Mikai giggled as she looked at her two guests. Saki Himitsu, her fellow Jõtaider and 'rival'. Well, that was kind of what they were at this point, no? She fought for what she believed in, and so did Saki-senpai. And beside her was Hayato Koizumi, JõtaiKiller and general edgelord, who was currently burying his hand in his face thanks to the fact that his partner hadn't bothered to tell him anything. Which wasn't an uncommon trend, considering the way that she loved to get on his nerves and generally be a nuisance.



"You really don't have to phrase it that way, Mikai." Saeko said from her spot on the couch, softly waving to her Senpai and her edgy friend, with Saki waving back in turn. "It's just that... Well, Yumeko's been such a great help. If something happens while she's away, I'd rather want you guys to work with Mikai than to be informed later and end up fighting against her." She explained, putting her hands on her lap. "That's fine. Right?"



"It is." Saki said, gently patting Mikai on the head as she went to take a seat on one of the nice chairs. Nice, soft and comforting. Perfect for her to rest in as they got comfortable. "Though I wouldn't be so sure about him. You know what he's meant to do, don't you?"



"I can hear you, damnit!" Hayato shouted, before just letting out a frustrated sigh. "I can choose to put the mission aside for now. Especially since Lady Hopper is still busy trying to figure out the best route towards her eventual objective." He explained, taking a seat as well. On the same couch as Saeko, who he sat as far away from as possible. While a soft blush coated his cheeks.



"You really should just talk some sense into her." Saeko said, smiling as Mikai took a seat between her and Hayato. "Based on what Lady D'Or told me, you should be able to negotiate with her. She is still the same woman that held such a close bond to her, after all."



Hayato rolled his eyes. "You try and talk to a woman that barely shows up." He muttered, while his eye drifted towards the TV in front of them. There was something... peculiar about it. But he couldn't put his finger on what or why. Best to just keep himself ready for something terrible.



Not that he had the chance to keep on guard, because Mikai pulled both him and Saeko into a great big hug. "Ehehe. I heard you two were really good at working together while you were trying to save me! I didn't think you'd make a friend like him, Saeko! He's all sorts of rude and loud and mea... Oh, but that's you as Spider, isn't it?" So innocently insensitive.



Both Saeko and Hayato felt their blood boiling as they collectively bonked Mikai on the head. "Mikai, please think before you speak." Saeko said, as she kissed the spot that she had bonked moments later. Just to make sure she hadn't actually hurt her.



"I swear. If you start imagining me in that outfit, Ero's going to find out. And she's going to figure out a way to stuff me into it." Hayato muttered. It was bad enough that he was forced to be stuck with a pair of massive tits far too often. It was even worse knowing that his partner would love to enable more and more instances like it. All because it was too fun to pass up.



Saki snickered as she pulled out her phone, quickly flicking to a particular account on a lewd service. One that Hayato was grimly familiar with. "It seems like she's already cooking up ideas." She said, showing him all the pictures displayed on screen.



Pictures that depicted his fat-breasted form and how many different outfits he could fit into. Three of which corresponded to the main enforcers of Golden Freedom as well as their leader. Thankfully, she had skipped over Cobra. Which... also served to embarrass him further. She had intentionally skipped over the one male...



"I really need to wipe her data banks and figure out a way to stop her from being so perverted." Hayato muttered as he buried his head in the palms of his hand. All to try and forget what he had seen.



As the girls chuckled and laughed at his pain, the TV started to spark. Turning on and revealing a top hat that looked eerily familiar. And only one person was able to actually notice the hat on the screen, since she wasn't fully occupied with the devious bullying.



"That hat... Lumiel!" Saki cried out as she tried to manifest her cane. As it turns out, Saeko was right to be wary. There was just one tiny problem with her attempt to arm herself and protect her friends...



Namely the fact that by the time she noticed the hat, it had already turned its hole towards them, and begun to suck them in. Mikai went in first, with Hayato popping in seconds later since he didn't have time to adjust. Saki followed suit after them, leaving just Saeko...



She could stay in this living room. She could avoid the same fate that the others had been subjected to. But then she'd be letting down Mikai... No, she'd be letting herself down. So instead of using her powers to keep sticking to the furniture, she jumped.



Straight into that hat, as she was slurped into the world inside the TV...



---



"Welcome, welcome. Jõtaiders, Killer and Spider. I hope I didn't interrupt any kind of intimate fun. Now that would just be terribly unpleasant."



Lumiel grinned, as he bowed in front of the pile of heroes that he had pulled from the real world. Honestly, pulling them here had been way too easy. But it wasn't like he was going to complain.



The four friends were currently lying in one big pile, with Hayato groaning as he was sandwiched in between Mikai and Saki with a bit of Saeko on top. Though that didn't stop him from picking up on the devious bastard's teasing. "The only kind of intimate fun happening here is when we fill you with holes, Darkness!"



"Charming." Lumiel snarked as he tipped his hat. "Now, while I would love to ruin you all permanently, considering what a pain in my ass you've all been... I'm afraid I just can't do that. My plans are quite rigid, you must understand." He explained, before a glint appeared in his eye. "That does not mean you are safe, however. I think it's time that we play a little game. A fun time, between the six of us."



"Six?" Mikai asked as she pushed everyone else off her back, not too bothered about being partly flattened. "I only see five. Unless you're pulling Chimera out of me, that'd make six."



Lumiel snapped his fingers, and a massive die appeared in Mikai's hands. A slightly furred die, with Chimera's face on it. "She doesn't count. But thank you, I did almost forget about her." He said, before clearing his throat. "OVERLORD! IT'S YOUR CUE!"



A beam of bright light slammed down from above, turning several hues of blue before Overlord Helheim burst forth, prompting a soft clap from Mikai as she was very pleased with the flashiness of the entrance.



"Ahahaha! Jõtaider! JõtaiKiller! You now stand before King Overlord Helheim!" Helheim laughed, as he was wearing a crown and everything. "Apologies, Lumiel. I was busy with my daughter." He said to his partner, not even bothering to whisper to try and keep that a secret.



Lumiel narrowed his eyes. "She's not your daughter, she's a construct made from that girl's powers." He said, before just shaking his head and twirling his hat. All so its powers could spread out behind him, quickly filling out the surroundings as he grinned from ear to ear. "The game we'll be playing is a simple one. I call it... Mimoto Party."



Hayato felt his blood freeze at the mention of the game's name, with Saki trembling in fear. Mikai and Saeko, meanwhile, just blinked in response. What was so chilling about this game to the point where both of them reacted like this?



"Aha. I see you're familiar with the concept. Without further ado, let's just make sure that you're all dressed to impress." Lumiel laughed, while snapping his fingers once again. He wasn't going to let any of them go around wearing their normal clothes. That'd be rather disappointing. If they were going to be playing a fun game with him, then they needed to look the part of wonderful contestants.



One by one, they were each made to wear a different outfit. Whether it was a set of plumber's overalls for Mikai and Saki that matched their respective colors, or a set of princess dresses for Saeko and Hayato. Which naturally prompted to latter to try and cuss out the bastard that had thought to inflict this upon him.



"Oh. OOOOOOH." Mikai suddenly realized what was going on, as she gazed at Saki. "I didn't know you played games, Saki-senpai." If she played a lot of good ones, maybe they'd be able to get a little closer!



"Later, Mikai. Focus on what's in front of you." The stern-hearted Student Council President said, as she glared towards the man that had forced them all into these humiliating outfits. "What's the goal? Stars? Points? Hotels?" She needed to know what she was competing for. So she could do her best to aim for the top and hopefully get the chance to destroy him once everything was over.



Lumiel maintained a terrible smile. "How about we leave that until the end? For now, just collect the most coins. Then we'll tally everything up at the end and decide a winner from there." He explained, before tipping his hat a little. "Now... Let this Mimoto Party begin!"



The competition began, and it was up to the four friends to endure it. No matter what might be inflicted upon them due to the devious bastard's machinations...



---



"Aha! Ahahaha! So you've landed on one of my spaces, Jõtaider!"



Mikai looked down at the mostly black and red and blue space. Huh. So that was a space that summoned Helheim. "Yeah, I did. What do I get?" She asked. She had been really good at avoiding bad spaces like this in the party games like this one. So she wasn't quite sure.



King Overlord Helheim scratched his chin a few times as he stared at his roulette wheel. Lumiel had told him that he should spin it to decide what the player should lose. Or what several players should lose. Buuuuuut... Where was the fun in doing that? He had a much better idea. One that would still play to the game's strengths.



"I grant you a boon, Jõtaider! Use it to steal the powers of your fellow players, and steal their fortune while you're at it!"



The Prime Darkness' chest opened, as a spark flew down into Mikai's hands. And with that, he vanished, leaving behind a manifestation of his Virus. Allowing her to transform into a version of him...



Right then and there, as the spark immediately spread through Mikai. She let out a mighty howl as her body mechanized in an instant. Replacing her flesh and her short stature with a taller and mightier mechanical mess, a mighty robotic lion standing tall as she was consumed by the Helheim Virus.



"Great! Just great!" Hayato shouted, as he was just a few spaces in front of Mikai. He was already in the negatives, which should've been a statistical anomaly. But noooo. She just had to be infested by Helheim and make his life worse. Especially as he heard her roll that die...



Which bonked right off his head as she just happened to toss it in his direction. And then a second one, which really made his head hurt and also made it impossible for him to see what was happening. All that he knew at the moment was that the world was spinning...



"Hayato!" Saeko cried out as she watched the oversized leonid approach the edgy boy. Normally, she'd close her eyes. Because his fate was going to be gruesome. But since this was a game, maybe it wasn't going to be as bad?



The Helheim-ized Mikai panted and let her hot and heavy breath pour out as she hovered over the stunned boy. Only to then counteract her incredibly scary appearance by picking him up and squeezing him tight.



A soft crack echoed, and Hayato was forced to scream in pain. Right before being let down on his feet once more, left with an even greater debt and an inability to roll. Lucky him...



Saki couldn't help but chuckle a little as she watched it. She was safe, Mikai had only rolled... so... wait. Hold on, she was-



The golden girl had miscalculated how many steps Mikai had rolled, and ended up getting the exact same treatment. A painfully strong hug, one that stunned her and drained her. Which didn't get any better as the effects of the virus ran out, leaving Mikai to shrink while still hugging her Senpai...



"Ehehe..." Mikai blinked and noticed what she had done. Blinking a few more times before returning to nuzzling her Senpai. Well, if she was stuck on this space for a bit longer, better just hug her.



Saeko shook her head, hoping that they were going to be able to endure all of this a little longer.



---



"What. The fuck."



Hayato didn't have any better words to describe what he was looking at. Most of the mini games that they had been through at this point weren't too strange. But this latest one was. It all revolved around inflating an inflatable copy of Cobra. And the hose was attached to... His bulge.



"Yeah, uh..." Saeko muttered, blushing as she stared at the very peculiar looking balloon. "I... Can we actually do this?" She asked, turning towards Saki and Mikai. Hoping that they had some sort of thoughts on the matter of this strange display. Hopefully they were restrained enough.



Unfortunately, she was greeted by the sight of the two girls furiously pumping more and more air into the inflatable bastard. With Saki being more successful in that regard. Pumping like her life depended on it.



"You're so quick, Senpai!" Mikai gasped and panted as she did everything that she could do to keep pace. She didn't want to lose to her Senpai. Not when she was this close to being in the lead. She had almost overtaken Saki, so she was going to do it. This time, she would win!



Saki laughed as she pumped even harder, a golden glint in her eye. "You will not be taking this victory, Mikai! IT WILL BE MIIIIINE!" She shouted from the depths of her soul, as she slammed the handle down on the pump. Right as she had pumped far too much into the balloon, ensuring her victory as it popped!



The other three competitors were blown away by that pop. But unfortunately for Saki, she was greeted with something terrible as a reward for her victory. And what was that horrible, terrible, awful reward?



Simple. The Cobra balloon wrapping around her and tightening until she looked just like him. Bulge and all, as she found out by rubbing her crotch for a second to check.



Hayato watched as the golden girl, trapped within latex that was meant to represent Cobra, started throwing a fit. And for once, he wasn't too disappointed in the fact that he had lost.



For now, he had to try his best to keep up his gameplay. So he could take the win. So he could avoid being subjected to all sorts of stupid nonsense at the hands of this awful game!



---



Saeko blinked a little as she found herself at the start of a racetrack. With Mikai, Saki (who was still grumbling inside her Cobra Suit) and Hayato all mounted on a set of skateboards pointed away from her. "Eh? What am I supposed to do? Catch up to them?" She asked, as it didn't quite make sense to her yet.



Lumiel's answer to her question was simple. He floated above her head, on a cheeky cloud with his smug face plastered across it, and he started to tilt a watering can. Letting dark liquids pour down on her, watering so that she could 'grow'.



The lavender-haired girl trembled all over as she was getting absolutely soaked. All while she could feel her body bulging. Growing. And a hunger filled in her stomach. A great big hunger...



A hunger that was so great that Saeko didn't even flinch when her face split apart, turning into one big pair of lips while the rest of her expanded even further. Right up until the moment she towered over the other competitors, her skin having turned deep green to reflect her new state as a ravenous plant. And like any ravenous plant, she just wanted to do one thing. She wanted to EAT.



"Fuck this." Hayato proclaimed as he immediately started to skate as fast as he possibly could. He knew exactly what was going to happen if he slowed down, and he wasn't going to let that happen to him!



Saki followed suit behind him, even using a bit of her power to make her skating more smooth. But Mikai was slow on the trigger, mainly due to the sheer sense of awe that filled her heart when she stared at Saeko. She couldn't stop herself from staring as she opened up that big mouth and started to hover over her. "Oh my, what big teeth you have, Saek-"



*CHOMP*



Mikai got chomped. Swallowed by the oversized plant, who looked a bit bulgy as she licked her big lips. It was a very nice meal. A very delicious meal. But she wanted more. Which was why she started to chase after the other two competitors. She wanted moooore.



"C-C'mon, damnit! Why was I dressed like a Princess in the first place?!" Hayato shouted as skating with heels was a terribly difficult task to master. And he didn't have time to adjust or anything. Especially not with that beast coming closer and closer with every second that passed. He had to skate faster. Faster, faster!



But it was that need to hurry that ended up doing him in. His heels shattered, and he was left to tumble and kiss the ground. At least, that was the idea. But Saki managed to catch him as he was wiping out, before lifting him into her arms. Which... Was only slightly preferred to being smashed against the ground.



"WHY DOES THIS ALWAYS HAPPEN TO ME AND NOT TO ANY OF YOU!?" Hayato shouted as Saki kept her grip on him tight, his position bringing him nothing but shame and disgust. He wanted nothing more than to be let go..!



Saki gazed upon the edgy boy and softly smiled. "Maybe it's because you're rather adorable when you whine." The cobra-suited heroine said, promptly shutting Hayato up as she continued to hold him like a bride. "We're almost at the finish. All we have to do is-"



*CHOMP*



Unfortunately for the two remaining contestants, due to focusing too much on what was coming up ahead and not on what was going on behind them, they didn't realize that the oversized predatory plant had caught up to them. And thus Saeko ate them both at the same time and collapsed onto her butt, laughing as she patted her engorged and swollen tummy...



Not that they would stay inside her. Nor that Saeko would stay as a plant. As soon as their surroundings turned back to normal, Saeko was forced to cough up all three of her friends, each of them covered in slobber. And she was forced to come to terms with the fact that she had just eaten all of them. Something that made her profusely apologize with the biggest blush on her cheeks that she could possibly manage.



She had won that minigame, despite the humiliation that it inflicted upon everyone. If she could just keep up this performance for the last few turns, then she would be the winner...



But what would the winner even receive...?



---



Hayato grit his teeth as it was his turn to roll the die. Looking to his left, he saw Saki about to get a bunch of coins from the nearby bank (and a kiss from Neoheim, why the hell was she here and why was she the bank attendant?!). On the right was Saeko, holding a spraycan that would make it impossible to steal from her. And Mikai... Well, she was somewhere else. Probably just enjoying the experience despite how utterly ridiculous it was.



If he just rolled safe, he would be able to win. Assuming the game was all about how many coins one could amass through winning games. Sure, Saeko and the others had been able to gain more through strategic victories and events on the board. But he was the one in the lead. He just had to roll the right numbers, and then..!



"Come on!" Hayato shouted as he tossed the die at a nearby wall, letting the die bounce right back at his face. Thankfully, he was quick enough to dodge out of the way of it. Saving him from being clocked by it, and letting him watch the number as it landed...



He landed on... A space with a hat on it. Ah. Ah fuck, that's not good-



Just like that, a hat pulled up around Hayato, and he was deposited at the side of the board. Not only that, but he was clad in a bunny suit... And had a massive set of fat tits again, this time not due to using Tithoth but rather due to that bastard Prime's abilities.



"I'm going to ki-" Hayato jittered as his eyes suddenly turned into happy hearts. "Kiss you, Lord Lumiel!" She giggled, finally aware of her gender being flipped and how she had become a good and loyal bunny for the duration of this event. All thanks to Lord Lumiel, ehe!



Lumiel smirked as he put three dice down in front of his lovely new assistant. "Welcome to Chance Time, my sweet little bunny. All you have to do is toss these three, and we'll see what happens. Who will be involved? What will be exchanged? And who might snatch defeat from the jaws of victory? All of that is up for you to roll for, my dear."



"Ehehe, to be graced with such an important role! You shouldn't have, Lord Lumiel!" If Hayato could control her body at this moment, she would've probably screamed. But the power that Lumiel held over her kept her docile, giggly and extra busty, her bosom bouncing up and down in delight as she picked up the two dice that were meant to represent the players.



And she stacked them on her bust, before going 'boing!' and jumping into the air a little, sending both flying into the air. She didn't know what they were going to land on, and that was the most exciting part. She couldn't wait to see what it'd be like. It'd probably have fun results!



"Whoa. Why does he always get the big boobs?" Mikai muttered as she completely ignored the dice falling from the sky. "Is it because he's tapping into the power of a bad guy-" She tried to figure out why exactly this phenomenon repeated, only to be clocked over the head by one of the falling dice.



"Mikai, this isn't the time to make breasts seem ev-" The tittest of the three girls said, before Saeko herself was clocked over the head by a die as well. Leaving her to collapse right by Mikai, both having chickens spin around their heads.



Yet, she wasn't the one that had been rolled. Neither was Mikai. The two that had been rolled with the two character dice were both Saki and Hayato. Maybe it was just Lumiel's way of messing with them.



"Ehehehe. I wonder what she'll give me? Or what I'll give her?" Hayato giggled lots and lots as she reached for the last die, giving it a good spin as she gently tossed it slightly into the air, before slamming into it with her plump bun butt to launch it towards the last competitor!



Saki narrowed her eyes as she quickly moved to block it, the die grinding against her hand as it kept on spinning despite making contact with her hand. She wasn't going to let it hit her. She wasn't going to-



She let it slip, and she was clocked across the head as well. Knocking her onto the floor as cartoony copies of Yuuki and Saeko danced around her head, showing that she needed a moment to recover as well.



Though at least she could breathe easy. Because she had won that exchange. The die had rolled on a result that meant that all of Hayato's cash went straight to her, causing her pockets to comically inflate as she continued to lie there on the ground.



Hayato giggled as she scratched the back of her head and stuck her tongue out. "Tehe." She chimed, as she had just messed the game up for herself. Oh well. That was the nature of Lord Lumiel's Chance Time. You win some, you lose it all!



Then realization dawned in her eyes. His eyes. He had returned to normal... Well, barring the fact that his body was definitely still mostly female. His junk was back, thankfully, but that didn't stop his body from being so painfully feminine. It was even worse than the few times that Ero forcefully uploaded him into copy versions of her body so she could try out different makeup techniques.



"I'LL KILL YOU FOR THIS, PRIME!" He screamed, causing his breasts to bounce all over the place in response to his rage. He wasn't going to take this humiliation. The second he had the chance, he was going to make that bastard choke on his own hat! And he was going to make sure that he didn't get back up again!



He had to win now. Despite the massive setback, he had to win! So he could make him pay!



---



"Well, well, well. You all performed rather adequately. Not amazingly, I'm not going to tell you something so plainly false. But you did well enough."



Lumiel smirked as he looked at the pile of idiots that were currently wiped the fuck out. Whether it was Saki who was still stuck being shorter than she was meant to be, due to being stuck in the Cobra suit, or Saeko who was still hungry due to her temporary transformation into a ravenous plant, or Mikai who felt the need to hug so tight like she didn't have any fleshy restraints, or Hayato being forced to press his face into his tits. Every single one of them were completely tuckered out due to the abuse that they had been forced to endure.



"Ahaha! What a wonderful game, what a delightful game!" King Overlord Helheim laughed, before looking at Lumiel. "So, who won? More importantly, what do they win?" He was too excited to give them a little boon. A tiny benefit for enduring all this torture. It was in his programming. To reward such a struggle like this, because it had shone so brilliantly.



Lumiel rolled his eyes. He did promise that there would be a winner. Well, then he was going to give them an appropriate reward. "The winner of this Mimoto Party is-"



"LUMIEL YOU LANKY PRICK, YOU STARTED THIS PARTY WITHOUT ME?!"



Ah. There was his cue. Good, he didn't need to hand out any reward. He merely had to snap his fingers, as the pile of contestants were very quickly sucked by the same screen that had sucked them in here, depositing them back into the real world.



All as Kimiko, clad in a dark set of overalls, and Tsukiko, clad in a silver dress, approached. With the former being beyond furious. "YOU TOLD ME THAT YOU WERE GOING TO WAIT FOR ME! YOU BASTARD!"



"My my. But I thought Lady Cepha grounded you. So why should I give you any kind of fun?" Lumiel said, smirking a little too potently. Especially as Kimiko grew angrier and angrier.



Only for Helheim to bonk him on the head, forcing him to wear a dress as well. All while King Overlord Helheim stood tall in overalls of his own. "...Helheim, we need hosts to play this game."



"NONSENSE!" He laughed. "We can play with ourselves as contestants. Come, Young One! Let us enjoy the festivities!" Lumiel had wormed his way out of one conclusion, he wasn't getting out of a second one.



Kimiko laughed cheerfully as her mood did an instant 180, completely ignoring the fact that Mikai had just been there. She was going to have lots and lots of fun.



And those four friends? Well, they were going to need a lot of time to recover after all of that. And a single thought was shared between them.



They were telling absolutely nobody about how all of this had gone...
